R2A20114BFP#W5

Overview

The R2A20114BFP#W5 is a Power Factor Correction (PFC) controller from Renesas Electronics Corporation, designed for continuous conduction mode (CCM) applications. It operates with a fixed switching frequency of 78kHz and supports a supply voltage of 24V. The device is housed in a 40-LQFP package measuring 7x7 mm, suitable for surface mount technology. It functions within an operating temperature range of -40°C to 125°C and features a feedback voltage of 2.5V ± 1.5%. This component facilitates efficient AC to DC conversion.

Feature Summary

• Enables precise AC to DC conversion through integrated power factor correction control
• Supports continuous conduction mode operation for stable power delivery
• Utilizes a lead-free LQFP package for reliable surface mount integration

Applications

• AC to DC power supply systems requiring high efficiency
• Industrial equipment power management modules
• Consumer electronics power adapters

Procurement Notes

Verify the obsolete part status before procurement planning. Confirm the 40-LQFP package dimensions and RoHS3 compliance requirements. Ensure compatibility with existing 24V supply designs. Check for authorized distribution channels due to end-of-life status. Validate thermal performance within the specified -40°C to 125°C operating range for your specific application environment.

Selection Notes

Select this component for designs requiring fixed-frequency CCM PFC control. Consider the 78kHz switching frequency for EMI filtering requirements. Evaluate the 40-LQFP footprint against PCB layout constraints. Assess the 2.5V feedback reference accuracy for precision regulation needs. Verify that the 24V supply capability aligns with system power architecture.

Part Context

This IC belongs to the Renesas PFC controller family, specifically optimized for continuous conduction mode applications. It addresses efficiency standards in power conversion by correcting power factor. The 40-LQFP package provides adequate thermal dissipation and pin count for complex control loops. It represents a specialized solution for dedicated power management tasks rather than general-purpose processing.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative sourcing requires careful evaluation of functional equivalence and availability.
